This isn't done but here you go. Only arrow keys to move, no WASD. That's in a more refined version that isn't finished yet. Click to shoot your one and only gun, a SMG. I'm allowed to have somewhat realistic guns, right? Press v to stop the background. You can't restart it though.
I started making this game a long time ago. The idea is that you shoot your evil twin, I guess... I think that this was supposed to be a horde game. I'm working on a better version so consider this a beta. Your evil twin can't die, you don't take damage, and the way the gun fires isn't great. I would tell you enjoy, but you probably won't anyway. Also new intro that's in a lot of my projects that died and weren't posted. Bye. Wow this game is so cool.
